Description

Technical Field

[0001] This utility model relates to a clamp, and more particularly to a taphole clamp, belonging to the technical field of blast furnace taphole plugging equipment. Background Technology

[0002] After the blast furnace has finished tapping iron, the taphole is filled with taphole clay. The taphole clay forms a protective layer at the taphole, which can resist the scouring and erosion of high-temperature molten iron and slag, extend the service life of the taphole, reduce the number of taphole repairs and replacements, reduce production costs, and form a sealed blockage at the taphole to prevent molten iron and slag from continuing to flow out, ensuring stable pressure inside the blast furnace and normal production order.

[0003] Currently, the filling process of mud guns often uses clamping or suction methods. However, since the mud guns on site are stacked in multiple disordered blocks, it is not possible to quickly and accurately insert the clamps into the side of the mud guns when clamping. The suction method also requires finding the horizontal plane of the mud guns, which makes it difficult to quickly remove the mud guns, thus affecting the filling speed.

[0004] To address this issue, a clay clamp was designed to optimize the aforementioned problems. Utility Model Content

[0005] The main purpose of this utility model is to provide a clay clamp to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved by adopting the following technical solution:

[0007] A mud clamp includes a box body, a rear end cover installed at the top of the box body, an installation component connected to a robot arm at the top of the rear end cover, an installation plate installed at the bottom of the box body, a front end cover installed at the bottom of the installation plate, and a conical auger drill bit evenly installed in a circular array at the bottom of the front end cover. A rotating component for controlling the synchronous rotation of the conical auger drill bit is provided on the installation plate and inside the box body.

[0008] Preferably, there are three sets of tapered auger drill bits, and the tapered auger drill bits are of the same length.

[0009] Preferably, the mounting components include a support column, a robot flange, and an angle aluminum cable support block. The support column is evenly fixed to the top of the rear end cover. The robot flange is provided between the tops of the support columns and parallel to the rear end cover. An angle aluminum cable support block is provided on the outer side of the top of the rear end cover.

[0010] Preferably, the rotating assembly includes a reducer, a servo motor, a drive gear, a driven gear, and a collet holder. The reducer is mounted on the top of the mounting plate, and the servo motor is mounted on the bottom of the housing. The output shaft of the servo motor is connected to the drive shaft of the reducer. The output shaft at the bottom of the reducer extends to the bottom of the mounting plate. The drive gear is mounted on the output shaft at the bottom of the reducer. The driven gears are evenly rotated in a circular array at the bottom of the mounting plate, and the driven gears mesh with the outer sides of the drive gears. A collet holder is mounted on the bottom of each driven gear. The top of the tapered spiral drill bit is mounted inside the collet holder.

[0011] Preferably, force gauges are evenly distributed at the bottom of the front end cap, and the force gauges are located between adjacent conical auger bits.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention features a conical spiral drill bit evenly arranged in a ring array on the outer side of the front end cover. A rotating assembly consisting of a reducer, servo motor, drive gear, driven gear, and collet holder controls the forward and reverse rotation of the conical spiral drill bit. When the device is used to pick up the stemming material, controlling the forward rotation of the conical spiral drill bit allows it to quickly drill into the stemming material and grab it. When the stemming material is moved to the stemming material loading port, controlling the reverse rotation of the conical spiral drill bit allows the stemming material to be withdrawn and dropped, thus improving the stemming material loading speed and increasing its practicality.

[0026] Example 1

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment proposes a clay clamp, including a box body 1. A rear end cover 2 is installed at the top of the box body 1. The top of the rear end cover 2 is provided with a mounting component that connects to a robot arm. A mounting plate 3 is installed at the bottom of the box body 1. A front end cover 4 is installed at the bottom of the mounting plate 3. A conical spiral drill bit 5 is evenly installed in a circular array at the bottom of the front end cover 4. A rotating component 6 for controlling the synchronous rotation of the conical spiral drill bit 5 is provided on the mounting plate 3 and inside the box body 1.

[0028] Before use, the clamp is connected to the robot arm using the installation component. Then, the robot arm controls the clamp to move above the mud. Next, the robot arm controls the clamp to move vertically towards the mud. After the conical auger 5 contacts the mud, the rotating component 6 controls multiple conical auger 5 to rotate clockwise simultaneously. The conical auger 5 rotates and inserts into the mud. When the mud is in contact with the bottom of the front end cap 4, the rotation of the conical auger 5 is stopped. The robot arm controls the mud on the clamp to move towards the mud loading port. When it reaches the loading port, the rotating component 6 controls the conical auger 5 to rotate in the opposite direction, ejecting the mud and dropping it into the mud loading port, completing one complete cycle.

[0029] Example 2

[0030] The solution in Example 1 will be further described below with reference to its specific working method.

[0031] like Figure 1 As shown, in a preferred embodiment, based on the above method, the conical spiral drill bit 5 is further provided in three sets, and the conical spiral drill bit 5 has the same length. The use of multiple sets of conical spiral drill bits 5 can improve the clamping stability of the drilling mud and prevent it from falling off during movement.

[0032] like Figure 2 As shown, in a preferred embodiment, based on the above method, the installation component further includes a support column 7, a robot flange 8, and an angle aluminum cable support block 9. The support column 7 is evenly fixed to the top of the rear end cover 2. The robot flange 8 is provided between the tops of the support columns 7 and parallel to the rear end cover 2. The angle aluminum cable support block 9 is provided on the outer side of the top of the rear end cover 2. When connected to the robotic arm, the installation of the clamp is completed by aligning the robot flange 8 with the flange on the robotic arm, and the position of the cable is supported and positioned by the angle aluminum cable support block 9.

[0033] like Figure 4 As shown, in a preferred embodiment, based on the above method, the rotating assembly 6 further includes a reducer 601, a servo motor 602, a drive gear 603, a driven gear 604, and a collet holder 605. The reducer 601 is mounted on the top of the mounting plate 3, and the servo motor 602 is mounted on the inner bottom of the housing 1. The output shaft of the servo motor 602 is connected to the drive shaft of the reducer 601. The output shaft at the bottom of the reducer 601 extends to the bottom of the mounting plate 3. The drive gear 603 is mounted on the output shaft at the bottom of the reducer 601. The driven gears 604 are evenly rotated in a circular array at the bottom of the mounting plate 3, and the driven gears 604 mesh with the outer side of the drive gear 603. The bottom end of each driven gear 604 is mounted with a collet holder 605, and the top end of the conical spiral drill bit 5 is mounted inside the collet holder 605.

[0034] When controlling the rotation of multiple sets of conical spiral drill bits 5, the servo motor 602 is started to control the rotation of the drive gear 603. The rotation of the drive gear 603 controls the simultaneous rotation of multiple sets of driven gears 604. The collet holders 605 at the top of the conical spiral drill bits 5 are respectively installed below the driven gears 604. Therefore, the conical spiral drill bits 5 can rotate simultaneously with the driven gears 604. The collet holders 605 are existing technology and are often used to position drill bits on CNC lathes. Therefore, this application will not elaborate on them further.

[0035] like Figure 4 As shown, in a preferred embodiment, based on the above method, a force sensor 10 is evenly provided at the bottom of the front cover 4, and the force sensor 10 is located between adjacent conical auger drill bits 5. When the conical auger drill bit 5 is rotated and inserted into the mud, the mud will squeeze the force sensor 10. The force sensor 10 is used to detect the pressure applied by the mud. When the specified pressure is reached, the force sensor 10 transmits the data to the controller, and the controller will control the servo motor 602 to stop rotating.

[0036] Example 3

[0037] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods.

[0038] Before use, the clamp is installed by aligning the robot flange 8 with the flange on the robotic arm, and the cable is positioned using the angle aluminum cable support block 9. During use, the robotic arm controls the clamp to move vertically towards the drilling mud. After the conical auger drill bit 5 contacts the drilling mud, the servo motor 602 is activated to control the rotation of the drive gear 603. The rotation of the drive gear 603 controls the simultaneous rotation of multiple driven gears 604. The collet seats 605 at the top of the conical auger drill bit 5 are installed below the driven gears 604, thus the conical auger... The spiral drill bit 5 can rotate simultaneously with the driven gear 604. The conical spiral drill bit 5 is inserted into the inside of the mud. During the insertion process, the pressure applied by the mud is detected by the force sensor 10. When the specified pressure is reached, the force sensor 10 transmits the data to the controller. The controller will control the servo motor 602 to stop rotating. At this time, the clamping is completed. Then, the robot arm controls the mud on the clamp to move towards the mud loading port. When it reaches the loading port, the conical spiral drill bit 5 is controlled to rotate in the opposite direction to remove the mud and drop it into the mud loading port, completing one complete cycle.

[0039] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
